Defatted bulk fish protein hydrolysates (FPH) exhibit many bioactivities.
Defatted FPH inhibit lipid oxidation.
Defatted FPH reduce blood pressure and glucose uptake into enterocyte.
Trypsin, Bromelain + Papain and Protamex lead to the most bioactive hydrolysates.
Prolonged hydrolysis gives higher bioactivities.
